纺粘法得以迅速发展的重要原因是它以合成聚合物为原料，该法利用化纤纺丝原理，在聚合物纺丝过程中连续长丝，经喷丝后成网后直接粘合而制成无纺布，制造方法非常简捷及快速，与干法无纺布加工技术相比，省去了纤维卷曲、切断、打包、运送、混合、梳理等一系列繁琐的中间过程，这种连续、大批量的生产最显著的效果就是使纺粘法产品成本降低、品质稳定、市场竞争力强，在用即弃和耐久性的各种用途中可进入到纺织品、纸张和薄膜的市场领域中。
An important reason is the rapid development of spunbond method with it to synthetic polymers as raw materials, using the method of chemical fiber spinning principle, continuous filament in the polymer spinning process, and directly bonded non-woven fabrics by net spinning after manufacturing method is very simple and fast, compared with dry processing technology spinning cloth, fiber crimp, cut off packaging, transport, and mixing, carding a series of complicated process is omitted, the continuous and batch production of the most significant effect is to reduce the cost of products, spunbonded stable quality and strong market competitiveness, in which various uses of abandoned and durability can be entered into the textile, paper and film in the field of market.
